TRF7970A in card emulation mode

$

I want to program TRF7970A in card emulation mode. I have one code for card emulation mode in which TRF796x is interfaced with MSP430G2553 microcontroller using SPI. I edited that code for TRF7970A EVM in which TRF7970A is interfaced with MSP430F2370 and I changed the interfacing also to the parallel interface. I checked the code on TRF7970A EVM with samsung galaxy S3 as a card reader but it is not working. I have checked the code, It is fine but the problem is that when the reader and tags come nearby at that time card should detect the RF field generated by reader and generate an interrupt to the MCU, and this is not happening,it seems that card is not able to detect the RF field and generate an interrupt.

It can be the issue that TRF7970A registers are not programmed correctly for card emulation mode.So I checked the settings of all the registers of TRF7970A and it is fine.So please help me in finding what could be the issue with the code.I have attached the code here.(Please visit the site to view this file)
